Still on extension? Here are the dates that matter.

A partnership or S-corporation return filed late runs $255 per partner or shareholder, per month or part of a month, for up to twelve months. A four-shareholder S corporation three months late is $3,060 in failure-to-file penalty alone.

An individual return runs 5% of the balance due per month, capped at 25%, and once the return is more than 60 days late the penalty is at least $525 or the full tax due, whichever is less. Interest on underpayments is running at 7%, compounded daily.

The extension gave you time to file. It never gave you time to pay — a balance due has been accruing interest since the original deadline either way.

We are a virtual-first firm. Most of our work happens by video and through a secure client portal, which means where you live matters less than whether we are the right fit. We prepare returns for clients across state lines, including the New Jersey, Pennsylvania and Philadelphia combinations that are routine around here.

We hold them because we would rather turn work away than file something we have not had time to read. If you are past a cutoff, call anyway — we will tell you honestly whether we can take it.
